It's the end of the Holocene in ten days and the last summer bloom that our generation will ever know. The long winter is approaching.
This is what the end of the Mayan Calendar represented. The ancient worldwide seafaring culture that taught the Mayans that calendar had figured out that the Holocene lasts 12,000 years and plotted the end of it so that future generations would know when the long summer would end.
The time of the grasshoppers is coming to an end. They had a good run of it and it was all a bit of a show about nothing. The time of the ants is returning, as it always has.
Our planet's natural state is much, much colder than this. The grasshopper thinks the sun will last forever but it must recede and go dormant again for long, long periods. The ant returns during this time to reclaim the earth, which he never really vacated.
The grasshoppers are Homo Sapiens. They jump around, mate, fight and die for a brief season but they must always be replaced by their sober, conservative, hardy and reverent cousins represented in the Neanderthal genome.
All of the paleoclimatological cycles are determined by magnetic cycles in the Sun that are reflected in the Earth which it shares a magnetic field with. Nobody knows what other changes accompany the ends of these cycles, at least nobody knows for certain. Not even Texas Arcane knows for sure what happens at this end. I have a hunch it won't be boring.
